A Application led December 21,1905. Serial No. 292,783.

To all whom it may concern:

Be it known that 1, GEORGE DUD'LEY'LooMrs, a citizen of the United states, residingat Tian, in the,

, county' of Senecaand Stateof Ohio, have invented a new and` useful Traction-Engine, of which the following-is a specication.` This invention relates to traction engines, and has for its principal object .to improve and simplify the c on'- struction and arrangement of the engine and traction mechanism, so that the fewest possible lnumberoi gears may be in mesh While the engine is employed for propelling the machine, and all of the gears in motion will be out of mesh when the engine is used for other purposes; that is to say, for operating a well drilling apparatus.

A further object oi the' invention is to provide a simple form of gearing connection between the propelling engine and driving shaft of the vehicle, and to permit the ready changing of speed when desired.

. With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out rin the appended claims, it being vunderstood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any ofthe ad vantages of the invention.

In the accompanying drawings Figure-l is a transverse sectional view through the rear portion of a traction machine, illustrating a traction mechanism constructed and arranged in accordance with the invention. Fig. 2 is a sectional elevation of the same Onthe'line 2-2 of Fig.` 1. Y

Similar numerals of reference are employed to indi# cate corresponding parts throughout the several figures oi the drawings..

vlVhile-the apparatus forming the. subject of lthe pres ent invention is applicable to all forms of traction engines,l it is found of especial value oruse in devices of that general class in which a derrick and drill operating mechanism are supported on a wheeled frame,` and driven by a steam or other engine, usually located at the rear oi the frame, the engine being employed for propelling the vehicle to and form the field` ofoperation,

and thereafter being utilized for manipulating the drilling mechanism.

In the present case the engine 10, which may be of any-desired construction, is supported on the frame 1l, and the engine is provided with a main or counter shaft 12, that extends transversely across the whole width of the trame., The frame is provided with suitable supporting wheels, including traction wheels 14, which are carried by axle members 15, and to each4 of these wheels is secured a master wheel 16. i The master wheels are in mesh withl pinions 17 on a shaft 18 that is connected by compensating gearing 19 to a largeg'eai1 20, and said gear 20 is revolved from the 'engine' atfdifferent speeds, in order to propel the vehicle.

On the main shaftl2 is feathered a double pinion 21--22, the two pinions being adjustable longitudinally of the vshait by means of a handled rod 23 that is provided with notches 24 for the reception of a spring locking lever 25 which is utilized to hold the gearsin position to which they may be adjusted, or the pinions Y may be separate from cach other and adjusted inde*n pendently. v l' v Arranged below the shaft 12 are Abearings for the support of a counter-shaft 26 arranged'parallel with'the shaft 12, and provided `withtwo gears 27 and .28, the gear- 27 being m'uch smaller in diameter than the gear 28, and boing arranged to mesh with the 'larger pinion. 21, while the gear 28 may mesh with the smallerpin- When the parts are in theposition shown in Fig. 1, both pinions 21 and 22 are out of mesh with the propelling gears, and the rotations ofthe shaft 12 may then be imparted through a drivev pulley 29 to the drilling mechanism near the opposite end ofthe frame., or to any other mechanism which it may be desired to operate, and thel engine is free to runavitliout any gears in mesh, or any unnecessary wear or friction on any Qfthe parts.

When the apparatus is to be propelled to or from 'the field of operation, .the rod 23 is moved to engage'the pinion 22 with the gear. 28, or the pinion 21 the gear 27. When the pinion 22 is in mesh-with the-pinion 28,

movement will be transmitted throlgh the countershaft to the main shaft 18,A andy the apparatus will be propelled at slovtT speed. To increase the speed, the

ing gears remain stationary4 andno gears 'are held while..

their-shafts rotate within tl1em solghattherejs no unnecessary friction toabsorb'any-o the power of the en# gine.,-
